Acoustic phonon-based interaction between coplanar quantum circuits in magnetic field
M. G. Prokudina, V. S. Khrapai, S. Ludwig +3
We explore the acoustic phonon-based interaction between two neighboring coplanar circuits containing semiconductor quantum point contacts in a perpendicular magnetic field B. In a…
Electrostatically defined Quantum Dots in a Si/SiGe Heterostructure
A. Wild, J. Sailer, J. Nützel +3
We present an electrostatically defined few-electron double quantum dot (QD) realized in a molecular beam epitaxy grown Si/SiGe heterostructure. Transport and charge spectroscopy w…
Radio frequency pulsed-gate charge spectroscopy on coupled quantum dots
D. Harbusch, S. Manus, H. P. Tranitz +2
Time-resolved electron dynamics in coupled quantum dots is directly observed by a pulsed-gate technique. While individual gate voltages are modulated with periodic pulse trains, av…
Electron-avalanche amplifier based on the electronic Venturi effect
D. Taubert, G. J. Schinner, H. P. Tranitz +4
Scattering of otherwise ballistic electrons far from equilibrium is investigated in a cold two-dimensional electron system. The interaction between excited electrons and the degene…
Asymmetric non-linear response of the IQHE
A. Siddiki, J. Horas, D. Kupidura +2
An asymmetric break-down of the integer quantized Hall effect is investigated. This rectification effect is observed as a function of the current value and its direction in conjunc…
Magneto-electrical subbands of freely suspended quantum point contacts
C. Rossler, M. Herz, M. Bichler +1
We present a versatile design of freely suspended quantum point contacts with particular large one-dimensional subband quantization energies of up to 10meV. The nanoscale bridges e…
